A Skeptical View of Israel's Iron Dome Rocket Defense System

Strange Attractor Re:Chain of reasoning (368 comments)

Reading TFA, that chain of reasoning occurred to me too. While I share some of TFA author's prejudices, I am persuaded by the comments here from folks claiming to be in Israel. I prefer judgement based on facts to facts based on values.

Ask Slashdot: Professional Journaling/Notes Software?

Strange Attractor Text file (170 comments)

You are right.

I use simple text files. I like them more than paper notebooks because:
1. I can edit them from anywhere that I can use ssh
2. They are easy to search
3. They are easy to back up

The comments (including the parent) that suggest simple text files and editors have all been modded down to 0. I don't understand why.

Australia May 'Pause' Trades To Tackle High-Frequency Trading

Strange Attractor Markets should be synchronous (342 comments)

Perhaps it would be better to accumulate orders without making them public for intervals of say a second or a minute. Then at the end of each interval execute buy and sell orders with overlapping prices.

Study Finds Methane Leaks Negate Benefits of Natural Gas-Powered Vehicles

Strange Attractor Short lived greenhouse gases help persuade (102 comments)

If people let enough methane escape to change the climate, it would be a short term disaster and teaching opportunity. It seems better than releasing enough CO2 to get the same change in temperature, because with CO2 the the effect would last so much longer.

Australian Teen Reports SQL Injection Vulnerability, Company Calls Police

Strange Attractor Lucky that it wasn't Intel (287 comments)

When Randal Schwartz probed security at Intel, they made him a convicted felon. See http://www.lightlink.com/spacenka/fors/

Morals:

1. Finding security holes is dangerous

2. You should buy AMD CPUs

How much of your media do you store locally?

Strange Attractor media is plural of medium (187 comments)

It's the physical stuff on which one conveys or stores information. My physical stuff is mostly in my house.

Elsevier Going After Authors Sharing Their Own Papers

Strange Attractor Physical Review is non-profit (259 comments)

Physical Review is published by the APS http://www.aps.org/about/ which "is a non-profit membership organization". I feel much better about such publishers than I feel about Elsevier.

Elsevier Going After Authors Sharing Their Own Papers

Strange Attractor Re:Wide Dissemination vs LockBox (259 comments)

That would be good.

I don't understand why the faculty of universities haven't already done it. University faculty provide the labor to produce and publish the papers (printing is irrelevant now), then publishers sell/rent those papers to university libraries. Professional societies live off of that income, and the likes of Elsevier extort higher prices for less good. The expense is crippling the libraries.

Just writing about it gets me angry.

It is like politics, blaming Cruz or Elsevier misses the point. The blame lies with the voters and university faculty; their choices create the market incentives that rational agents serve.

Why Amazon Is Profitless Only By Choice

Strange Attractor Did DEC ever pay a dividend? (258 comments)

I used DEC computers from 1975 through the 1980's till I switched to SUNs. It was a great company that made great machines. While I used their machines, they had never paid a dividend because they believed they should use profits to grow the business. I don't know if they ever paid dividends. I wonder how DEC's IPO price compared to what COMPAQ paid for the company at the end.

Two-Laser Boron Fusion Lights the Way To Radiation-Free Energy

Strange Attractor Half MeV Beam (140 comments)

See the nice wikipedia article at http://en.wikipedia.org/wiki/Aneutronic_fusion.

  Protons with a kinetic energy of about 500,000 electron volts have a good chance of producing 3 alpha particles with about 17 times as much energy when they hit a boron-11 nucleus. Unfortunately, a .5 MeV proton beam penetrating solid boron loses energy to electrons at about 100 times the rate that it produces energy via the induced fission. Thus you must move the electrons aside before you can start making money.

The Next Big Fiber Showdown: Austin

Strange Attractor Natural monopoly (230 comments)

Digging duplicate trenches to lay parallel fiber is wasteful. That's why utilities are "natural monopolies". Getting economic efficiency in such situations usually requires regulation or community ownership.

Exxon Charged With Illegally Dumping Waste In Pennsylvania

Strange Attractor A cube less than 6 meters on a side? (246 comments)

That's what I get for 189 tons of water.

Does anyone else get something different?

Chlorides, barium, strontium and aluminum? I suppose that it was not as bad as water from the Great Salt Lake.

Ask Slashdot: What Magazines Do You Still Read?

Strange Attractor IEEE is the dark side (363 comments)

I find that IEEE locks up research results that I pay for as a tax payer. It is a minor inconvience for me to use the library at work, but it would be prohibitive if I were a middle income indpendent scientist or engineer.

The IEEE also has policy statements that oppose policies that advance the public interest. Take a look at: http://www.ieeeusa.org/volunteers/committees/ipc/index.html and http://www.groklaw.net/articlebasic.php?story=20090922030639824

After 30 years, I dropped my membership. The IEEE no longer advocates or implements policy for the public interest.

Library Journal Board Resigns On "Crisis of Conscience" After Swartz Death

Strange Attractor Remember the MathWorld Story? (128 comments)

I took a look at http://en.wikipedia.org/wiki/MathWorld to remind myself about how CRC press treated Eric W. Weisstein (creator of MathWorld). CRC press is a division of Taylor and Francis. Whenever I get a request to referee for a Taylor and Francis publication, I decline and point the editor at the MathWorld story.

Don't do business with Taylor and Francis.

Could Twitter Have Stopped the Media's Rush To War In Iraq Ten Years Ago?

Strange Attractor Greatest Shame (456 comments)

I believed the adminstration's story 10 years ago. But six weeks after the invasion began, I knew I had been lied to. The great shame is that we (the US voters) voted in 2004 to let Bush stay in office after it was clear even to fools (like me) that what you accuse him of was true.

Texas School Board Searching For Alternatives To Evolutionary Theory

Strange Attractor Re:honestly? (763 comments)

You would lose your bet.
I would bet more than 60% percent of voting age Texans believe that heaven and earth were created by Jesus Christ's father less than 10,000 years ago.

What Early Software Was Influential Enough To Deserve Acclaim?

Strange Attractor Re:TeX (704 comments)

TeX, yes!

I wrote my first scientific article in Macwrite, my second in ditroff, and my third in LaTeX. Then I combined them into a dissertation. I chose to translate the fist two into LaTeX. My second choice would have been ditroff, and my third choice would have been to pay someone to type it all up. A better name for Macwrite would have been MacMemo. For anything longer than a page, it was awful. I don't know what value it has/had other than a cautionary tale for others to avoid.

I believe that after 30 years, it may be time for me to move beyond LaTeX. I'd like something I could program more easily. And I'd like support for describing function more than appearance.
